Description [src]
final class Adw.Breakpoint : GObject.Object
implements Gtk.Buildable {
/* No available fields */
}
Describes a breakpoint for AdwWindow.
Breakpoints are used to create adaptive UI, allowing to change the layout depending on available size.
Breakpoint is a size threshold, specified by its condition, as well as one or more setters.
Each setter has a target object, a property and a value. When a breakpoint is applied, each setter sets the target property on their target object to the specified value, and reset it back to the original value when it’s unapplied.
For more complicated scenarios, AdwBreakpoint::apply and
AdwBreakpoint::unapply can be used instead.
Breakpoints can be used within AdwWindow, AdwApplicationWindow or
AdwBreakpointBin.
AdwBreakpoint as GtkBuildable:
AdwBreakpoint supports specifying its condition via the <condition>
element. The contents of the element must be a string in a format accepted by
adw_breakpoint_condition_parse().
It also supports adding setters via the <setter> element. Each <setter>
element must have the object attribute specifying the target object, and
the property attribute specifying the property name. The contents of the
element are used as the setter value.
For G_TYPE_OBJECT and G_TYPE_BOXED derived properties, empty contents are
treated as NULL.
Setter values can be translated with the usual translatable, context and
comments attributes.
Example of an AdwBreakpoint UI definition:
<object class="AdwBreakpoint">
<condition>max-width: 400px</condition>
<setter object="button" property="visible">True</setter>
<setter object="box" property="orientation">vertical</setter>
<setter object="page" property="title" translatable="yes">Example</setter>
</object>
